我工作的asp.netmvc应用程序由csharp。我面临的问题，我找不到控件搜索输入类型文本框。
我搜索的行动控制器PendingRequests我找不到它。
我也搜索index.html，它不存在
那么如何获得搜索文本框请？
动作控制器

public ActionResult Index(string filenumber)
    {
        int employeeFileNo;
        string userRole;

      
        if (!string.IsNullOrEmpty(filenumber))
        {
          
            if (int.TryParse(filenumber, out employeeFileNo))
            {
                JDEUtility jde = new JDEUtility();
                userRole = Workforce.GetUserRole(employeeFileNo);

                if (!string.IsNullOrEmpty(userRole))
                {
                    var EmpName = jde.GetEmployeeName(employeeFileNo);

                    Session[SessionKeys.UserCode] = employeeFileNo;
                    Session[SessionKeys.Username] = EmpName;
                    Session[SessionKeys.RoleCode] = userRole;
                    if (userRole != RoleKey.REQ)
                        return RedirectToAction("PendingRequests", "WorkforceRequests", null);
                    else
                        return RedirectToAction("MyRequests", "WorkforceRequests", null);
                }
                else
                    ViewBag.errorMsg = "unauthorized user";

            }
            else
            {
                ViewBag.errorMsg = "incorrect file no";
            }
        }
        else
        {
            ViewBag.errorMsg = "unauthorized user";
        }

        return View();
    }

挂起请求视图

    ViewBag.Title = "Pending Requests";
    Layout = "~/Views/Shared/_Layout.cshtml";
}
